Introduction
1.3.6 Unipolar valve (P/N E2V**FSAC*)
Used with a compatible stator from the E2VSTA03**series. Unipolar electronic expan-
sion valve, managed directly by the controller, which guarantees precise refrigerant
fl ow even at low fl ow- rates. See the technical leafl et +050001680.

1.3.7 Ultracap module (EVD0000UC0)
The Ultracap module EVD0000UC0 is an optional external backup module for the
EVD Evolution driver that ensures the valves are closed in the event of a power fail-
ure. The module guarantees temporary power supply to one EVD Evolution driver
(single or twin) only in the event of a power failure, for enough time to immediately
close the connected electronic valves (one or two). It therefore also avoids the need
to install a solenoid valve in the refrigeration circuit, or a backup coil kit.

1.3.8 Ultracap module for unipolar valve (EVD000HAC0)
The Ultracap module EVD000HAC0 is an optional device used with the µChiller mod-
els equipped with an integrated unipolar electronic valve driver. This external backup
module closes the valve in the event of a power failure.
